Implementation Of The DIPSCAN Method To Estimate Boundary Dips In Complicated Structures By VSP Data

The knowledge of velocity model not even along well but at offset is key for building of VSP-CDP image<br>and tie of VSP and surface seismic data. And the task is more difficult in situations of lateral variations of the<br>media properties, that very typical for highlands. The quality of obtained image is in a straight dependence on<br>quality of reference model. And it is the main reason to obtain adequate reference model for offset-VSP<br>processing.
